ATTORNEYS Patented Mar. 2, 1937 UNITED STATES PATENT OFFICE TERIALS John Hughes, Rochdale, England Application July 28, 1934, Serial No. 737,367 In Great Britain July 29, 1933 1 Claim.

This invention of improvements in gilling machines and drawing machines for the treatment of fibrous material relates to gilling machines, worsted draw'frames and like machines for preparing fibrous material for spinning or other treatment or use.

The invention consists in top rollers which are provided for pressing or holding slivers or like bodies of fibrous material against bottom or lower rollers or belts or aprons in order to effect or to control the delivery or passage of or to draw, draft or extend the slivers or like bodies of material in gilling machines, worsted draw frames and like machines and are advantageous in comparison with the top rolle-rs hitherto employed for a like purpose in any such machines in being capable of hearing more steadily upon fibrous material between them and lower rollers or belts or aprons used with them and in being of simple and convenient construction and forming units or assemblages of parts easily applied in machines in which they are to be used and with little separation of parts easily removed from machines.

Other objects and features of the invention are set forth in the following description and the claim appended to this specification.

In the accompanying drawing in which parts already in use and in public knowledge are shown only in part but sufiiciently to show the application or connection therewith of parts provided according to the invention, Fig. 1 is an end elevation of a top roller. Fig. 2 is in part a side elevation of the top roller shown in Fig. 1 but shown broken to shorten the figure and in part a longitudinal section thereof taken on the plane indicated by the line II--II of Fig. 1. Fig. 3 is an end elevation of a top roller and Fig. 4 is in part a side elevation of the top roller shown in Fig. 3 but shown broken to shorten the figure and in part a longitudinal section thereof taken on the plane indicated by the line IV--IV of Fig. 3. Figs 2 and 4 are generally similar, the difference between the rollers being that that shown in Figs. 1 and 2 comprises ball bearings and that shown in Figs. 3 and 4 comprises roller bearings. The same characters of reference indicate corresponding parts in all figures and for distinction between parts in Figs. 3 and 4 and like parts in Figs. 1 and 2, some of the reference characters in Fig. 4 each include the affix or so that in great part the description of the roller in Figs. 1 and 2 comprising ball bearings may apply to that of the roller shown in Figs. 3 and 4 which comprises roller bearings.

Referring to the drawing for illustration, an arbor or axle I is provided which is movable up and down without being revolved and a revoluble boss or roller body or as shown two or more revoluble bosses or roller bodies 2 for bearing in use on fibrous material against a bottom or lower roller or rollers or a belt or apron beneath it or them is or are provided around that arbor or axle I and the part of the arbor or axle I surrounded by a boss or roller body 2 is shaped to be larger in diameter in a central part or other part 3 between its ends than in parts 4, 5 at opposite sides of that central or other part 3 as in arbors or axles already known and in use in loose boss top rollers. The part 3 larger ina central part or other part between its ends than in parts 4, 5 at opposite sides of that central or other part 3 may be formed in any way appropriate, for example by being formed or constructed with a short cylindrical part and 0ppositely tapering parts at opposite sides of the cylindrical part or with oppositely tapering parts joining or meeting by their largest parts or, as shown, barrel shaped or curvilinear in longitudinal section. The arbor or axle I is made subject to the influence of a weight or spring or weights or springs in any manner appropriate in any case, for example the ends in the case of a roller with a single boss or roller body, or in the center or at the ends or in the center and at the ends in the case of a roller with two bosses or roller bodies, or at the ends or between the bosses or roller bodies or at the ends and between the bosses or roller bodies in the case of a roller with three or more bosses or roller bodies. The drawing does not show a weight or spring as the application thereof with a roller forms no part of the invention. The arbor or axle I is, however, shown as formed in its middle part of smaller diameter in order there to receive application of a spring or weight. The arbor or axle I may be held against rotation, if desirable, by any means appropriate.

According to the invention, in a top roller for use in an intersecting gill box comprising upper and lower sets of fallers. or in a gill box with a single set of fallers or a worsted draw frame or like machine, there is provided for the or each boss or roller body 2 a sleeve 6 which, being provided on its exterior with ball bearings 8 as shown in Fig. 2 or roller bearings 8', 8" shown in Fig. 4 applied upon or around it and secured in position in any manner appropriate, is made to provide support and bearing for the revolution of the boss or roller body 2 and is itself formed with a cylindrical hole I or other hole adapting it to be applied around and made to oscillate about the middle of its length or a part near the middle of its length within limits upon a part of the arbor or axle I larger in diameter at the central or other part 3 between its ends than at parts 4, 5 at opposite sides of that central or other part 3 so that the sleeve 6 is made to fit upon and to be positioned with the necessary accuracy by the largest part 3 but to be capable of oscillation about it relatively to the length of the arbor or axle I within limits fixed by the wall of the hole I and the smaller parts 4, 5 of the arbor or axle I within it, so that within the limits so fixed the loose boss or roller body 2 can become adjusted to be revolved in any position relatively to the arbor or axle I while bearing steadily upon fibrous material or the roller or rollers or belt or apron beneath it. The sleeve 6 capable of being oscillated is held upon the arbor or axle I by an appropriate means and conveniently, as shown, and according to the invention, by a shoulder or collar 9 of the arbor or axle I at one end and at the other end by a spring clip I0 comprising arms II for gripping the arbor or axle I between the sleeve 6 and a shoulder or collar 9* on the arbor or axle I and preferably also a washer I2 around the arbor or axle I between the spring clip I0 and the sleeve 6. The arms II are provided by portions extending in symmetrical form from the ends of a connecting bar and bent in relation to the middle plane transverse to the length of that bar first inwardly in a curve, then outwardly in a curve, again inwardly in a curve and last outwardly. The arbor or axle I is formed near each end with a groove I3 extending around it to receive the clip I0 applied at that end of the arbor or axle I. Only one groove I3 is shown on the drawing. In a preferred construction the sleeve 6 capable of being oscillated and the boss or roller body 2 around it are contrived, as in the case shown by way of example, so that the sleeve 6 made oscillatable on the arbor or axle and the parts of the boss or roller body 2 around that sleeve 6, can be removed from the arbor I without separation of the sleeve 6 from the surrounding parts of the boss or roller body- 2. Around the sleeve 6 shown in Fig. 2, preferably by being forced thereon so as to remain in position, are fixed two inner ball races I4 in the case shown for two ball or roller bearings, and preferably rings or collars I5 for hindering the escape of lubricant at the ends of the sleeve 6 and there are applied around the inner ball races I4 the rings of balls and outer ball races I6 which, with a distance piece or tube I! between them are secured in and preferably forced into a sleeve I8 to surround them and furnished with annular collars I9 which are provided for hindering the escape of lubricant at the ends of the sleeve I8 and are preferably, as shown, grooved in their inwardly directed faces, and there is applied around the sleeve I8 surrounding the ball races IS an external sleeve 20 which is fluted or otherwise adapted itself to bear upon fibrous material in the use of the roller or is furnished with a surrounding sleeve or sleeves of leather or other material in order that a surface of the character requisite may be provided for bearing upon fibrous material in the use of the roller. In the case illustrated a band or sleeve 2| of leather is secured in any appropriate manner around the sleeve 20 and a second band or sleeve 22 of leather is secured around the first and, in the case of bands, so that the meeting place of the ends of the band 22 shall not lie upon the meeting place of the ends of the band 2I. Roller coverings or circumferential surfaces of other kinds may be used.

The sleeve I8 surrounding the ball races I6 and the external sleeve 20 surrounding it are secured together by any means appropriate and conveniently, as shown, by screws 23 applied in the external sleeve 20 so that their heads overlap the sleeve I8 surrounding the ball races I6 and preferably also by a peg 24 ensuring that the two sleeves I8, 20 shall be revolved together. Advantageously, as shown, the sleeve I8 is formed with a radial hole in which a peg 24 is inserted and secured by being driven into the hole to project outwardly from the sleeve I8 and the external sleeve 20 is formed internally with 001- lars 25 adapted to fit around the sleeve I8 and in order to receive engagement of the peg 24 for compelling the sleeves I8 and 20 to revolve together, at least one of the collars 25 is formed with a groove 26 and conveniently as shown each collar 25 is formed with a groove 26, the two grooves 26 being in line.

Except in that instead of the ball bearings 8 and inner ball races I4 and outer ball races I6 shown in Fig. 2, there are provided in the roller shown in Figs. 3 and 4 roller bearings 8 and 8", inner roller races I4 and I4 and outer roller races I6 and I6, the roller shown in Figs. 3 and 4 is constructed like that shown in Figs. 1 and 2. The inner roller races I4 and I4",are secured upon the sleeve 6 and the outer roller races I6, I6" are secured within the sleeve I8 with a distance piece or tube I 1' between, in the same way as the ball races I4 and I6 are secured upon the sleeve 6 and in the sleeve I8 respectively.

What I do claim as my invention and desire to secure by Letters Patent is:-

In a top roller for a sliver rubbing device, in combination, an arbor of barrel form having a part of maximum diameter intermediate its ends, an inner sleeve internally and externally of cylindrical form surrounding said arbor and fitting said part of maximum diameter, an intermediate sleeve surrounding and spaced from said inner sleeve, inner races fixed to said inner sleeve adjacent to the ends of said inner sleeve, outer races fixed to said intermediate sleeve adjacent to the ends of said intermediate sleeve, anti-friction elements received in said races, lubricantretaining collars at the ends of said inner sleeve, collars at the ends of said intermediate sleeve adjoining said first mentioned collars, said inner and intermediate sleeves, races, anti-friction elements and collars forming a unit removable endwise from said arbor without disturbance of said elements in said races, an externally fluted outer sleeve surrounding said intermediate sleeve, said outer sleeve being formed internally with grooved collars adapted to fit said intermediate sleeve and being provided externally with a covering, headed screws applied to the ends of said outer sleeve, the heads of said screws overlapping said intermediate sleeve, a peg fixed to said intermediate sleeve and engaging a groove in one of said last mentioned collars, said screws being removable to permit removal of said outer sleeve without disturbance of said unit, and instantly disengageable means applied to said arbor and normally retaining said inner unit against axial displacement on said arbor.
